Comparing: M7 vs. Type T-34 vs. Type 3 Chi-Nu Kai

Development started in 1941. Initially, the vehicle was developed as a light tank; however, as the model gradually received extra armor and armaments, it was reclassified as a medium tank. Production of the M7 started by the fall of 1942. However, since the M7 was inferior to the mass-produced M4 Sherman in all parameters except speed and dimensions, the production was stopped. A total of 7 vehicles were produced.

Among the 1,800 T-34 tanks supplied by the U.S.S.R. to China in the early 1950s, there was a number of T-34-76s. After the tanks saw service in the PLA, almost all of them were sent to North Korea. The usefulness of these tanks was extended by Chinese-designed upgrades, including a new engine and modernized suspension.

The Type 3 Chi-Nu Kai medium tank is a combination of the Type 3 Chi-Nu suspension and turret and the Type 4 Chi-To gun. Only one prototype was built. It was ready for trials in March of 1945.
